For example, a long call option with a delta of 0.30 would rise by $0.30 if the underlying asset rose in price by $1. Traders often refer to the sensitivity measure in basis points. A delta of 0.30 may be referred to as “30 delta.” iready fwps

"WebThe second derivative is f’’ (x) = 2, again by the power rule. Since 2 is always positive, we have f’’ (x) > 0 for all values of x. This means that f (x) is convex (concave up) for all values of x, and it opens upward. (using the S e c o nd Derivative Test) You … " - Derivative less than 0
